Overview
What's Simkube, Precious?
POV: Sam and Gollum are SREs using SimKube
SimKube is designed to allow users to simulate the behaviour of Kubernetes control plane components in a safe, isolated local environment. It is a "record-and-replay" simulator, which means that users can record the behaviour of a production cluster and then save that data for future analysis.
SimKube accomplishes this by running in a cluster with a real control plane; however, all pod behaviours are mocked out using Kubernetes WithOut Kubelet (KWOK). This means that anything that happens inside a pod can be simulated away. This enables users to simulate extremely large (1000+ node) Kubernetes clusters on a single EC2 instance.
The free version of the SimKube AMI includes a basic Kubernetes cluster running SimKube, along with all the tools you need to run and analyze your simulations!
Highlights
- Use SimKube to explore and optimize your Kubernetes clusters in a risk-free environment
- Perform cost forecasting or capacity planning by plugging in real instance type and pricing data from your cloud provider
- Simulate thousand-node Kubernetes clusters on a single EC2 instance

64-bit (x86) Amazon Machine Image (AMI)
Amazon Machine Image (AMI)
An AMI is a virtual image that provides the information required to launch an instance. Amazon EC2 (Elastic Compute Cloud) instances are virtual servers on which you can run your applications and workloads, offering varying combinations of CPU, memory, storage, and networking resources. You can launch as many instances from as many different AMIs as you need.

Usage instructions
To use this AMI, first launch a supported AWS EC2 instance with your chosen configuration. You will need SSH access to the instance: a security group that allows access over port 22 and either a public IP address or a way to access hosts inside your private VPC. The SSH username is ubuntu, and you will need a keypair configured on the host in order to access it.
The launched instance will have a running kind cluster with SimKube configured; you can use kubectl to inspect the state of this cluster and confirm that it works correctly. The launched instance also has the skctl CLI tool installed for interacting with SimKube.
You can now follow the instructions on https://simkube.dev/simkube/docs/intro/running/ to run your first simulation. If you have a trace file already, you can place it in /var/kind/cluster, and then use skctl run to start the simulation. If you don't have a trace file already, you can find some example traces at https://github.com/acrlabs/simkube/tree/main/examples/traces
